a flanged roller as at 45. The rollers 45 engage longitudinally extending parallel arcuate shaped seats or tracks 46, detachably mounted on the bracket 4'! fixed to the backwall H. The tracks 46 may be held to the bracket by any suitable fastening means, such as by the rivets 48. The radius of each track 46 is swung from the axis of the transverse shaft 35, hence the riser housing 2| can move fore and aft with reference to the firebox about the shaft 35.

Thus it will be seen when the locomotive and its tender are passing over curving track and the longitudinal distance between the twoincreases the riser housing 2| will rise on the tracks 46 moving in an arc from the axis of the hinge or shaft 35 thereby increasing the angle of inclination of the intermediate conduit section 20," which Q is of fixed or unvarying length, having the'effe'ct' motive and the trough section on the tender is provided by lateral movement of the intermediate section by reason ofits universal connections with the end sections.

Likewise the stoker conveyer of this invention responds to any other movement of the locomotive and its tender.

For example, in making up trains the coupling member between the locomotive and tender may be compressed, in, effect, shortening the distance between the parts. In

response to this movement the inclination of the intermediate conduit 20 will be lessened and the riser 2! will roll or slide downwardly on the tracks 46 moving closer to the backliead. When the coupling connection assumes its normal position the riser housing rises-,toits operative or normal position as shown on the drawing. Any vertical movement between the locomotive and tender is permitted by the flexible arrangement of the intermediate conduit 20 with theend sections, and should the vertical movement be such as to increase the longitudinal distance between the-parts this is then compensated for by fore and aft movement of the riser 2] onl'the tracks 46 In event it is desired to disconnect the tender from the locomotive and hence the trough I9 from the intermediate and forward conduit sections, this can be done-simply by compressing the springs 32, 32a of the latchesZl, 21a thereby disengaging the intermediate conduit tubular portion 26 with the spherical clamp-member 23.

The invention provides a simple, cheaply constructed and durable form of stoker conveyer free from telescoping or extensible parts and one wherein the fuelmay be conveyed from the trough l9 to the firing opening l3 through an enclosed passage having no openings therein to cause loss of fuel.

While only one embodiment of my invention is shown, it may be employed in -various forms within the scope of the appended claims.
